Abstract

Abstract Effective catalytic conversion of CO 2 into gasoline was investigated by one-pass operation using a serially connected flow-type reactor. Rapid CO 2 -reforming of methane into syngas was conducted by a newly developed Rh-modified NiCe 2 O 3 Pt catalyst at a low furnace-temperature around 400∼500°C. A high methane conversion was achieved by an in-situ beat supply due to catalytic combustion of added ethane or propane which is more combustible with higher combustion heat than methane. Thus obtained syogas or a CO 2 -enriched syngas was then converted into methanol on a novel highly active methanol synthesis catalyst, composed of Pd-modified CuZnCrGaAl mixed oxides, and the methanol produced was introduced to the successive reactor packed with a metallosilicate catalyst having MFI structure, and totally converted into gasoline with a high space-time yield and selectivity.
